Abstract

L'invention concerne une structure de déverrouillage pouvant être déverrouillée d'une main, la structure de déverrouillage comprenant : une colonne de limitation (221), une table de décalage (222) et une table de serrage (223), qui sont disposées sur une base d'étanchéité (22) d'un composant de corps d'étanchéité (20); une fente de serrage (321) disposée dans un couvercle en bec de canard (32) d'un composant manchon (30); et un bouton de libération élastique (33), le bouton de libération (33) comprend une table de limitation (331), un bouton (332) et un bloc de déverrouillage (333); la table de limitation (331) est pourvue d'une fente de serrage de table de limitation (3311) et d'une glissière de table de limitation (3312); un espace permettant à la colonne de limitation (221) de passer à travers celui-ci est formé parmi la table de limitation (331), le bouton (332) et le bloc de déverrouillage (333); et la colonne de limitation (221) peut entrer dans la fente de serrage de table de limitation (3311) le long de la glissière de table de limitation (3312) pour former un état de verrouillage, et peut également être séparée de la fente de serrage de table de limitation (3311) lorsqu'elle est poussée et pressée par le bloc de déverrouillage (333) de façon à retourner à la glissière de table de limitation (3312) pour former un état de déverrouillage. L'invention concerne en outre un ensemble manchon qui peut être déverrouillé d'une seule main, et un dispositif de perforation. En utilisant le bouton de libération élastique (33) et la table de décalage (222), lorsque le composant manchon (30) est maintenu d'une main, un utilisateur peut appuyer sur le bouton de libération (33) avec son pouce et décaler la table de décalage (222) avec son index de façon à déverrouiller l'ensemble manchon (30); et le bouton de libération (33) a une structure simple, et les coûts de fabrication et d'installation sont faibles.
